Fill with approximately 3 US gal (12 liters) of -58°F (-50°C)
propylene glycol based plumbing antifreeze. The UFC 211 and
UF 211 series models do not have enough internal space to
accommodate 3 gallons of antifreeze initially. Remove the plug
from the outlet stainless steel ex hose and drain some
antifreeze/water mix from the system into an empty container.
Add the remainder of the antifreeze into the internal prelter
cavity. The uid level in the system must be at least 2” above
the bottom of the internal prelter cavity. Reinstall the plug
into the outlet stainless steel ex hose.
Antifreeze level at
least 2" from bottom
